I'm trying to build an ios app using CMake, and I am running into a few warnings and errors. First, I'm getting this when I call cmake:
CMake Error in CMakeLists.txt:
Syntax error in cmake code when parsing string
<string>arxan.${PRODUCT_NAME:rfc1034identifier}</string>
syntax error, unexpected cal_SYMBOL, expecting } (48)
It still seems to build everything though, and I can run make. However, I get the following warning:
clang: warning: no such sysroot directory: 'iphoneos'
and error:
In file included from /Users/aottinger/TestFrameWorkiOS/AppDelegate.m:9:
/Users/aottinger/TestFrameWorkiOS/AppDelegate.h:9:9: fatal error:
'UIKit/UIKit.h' file not found
#import <UIKit/UIKit.h>
Here is my CMakeLists.txt:
cmake_minimum_required(VERSION 2.8)
project(auto_generated_xcodeproj)
set(NAME auto_generated_xcodeproj)
file(GLOB headers *.h)
file(GLOB sources *.c *.cpp *.cc *.m)
set(CMAKE_OSX_SYSROOT iphoneos7.1)
set(CMAKE_OSX_ARCHITECTURES "arm64")
set(CMAKE_XCODE_EFFECTIVE_PLATFORMS "-iphoneos")
add_executable(${NAME} MACOSX_BUNDLE ${APP_TYPE} ${headers} ${sources})
target_link_libraries(${NAME}

"-framework CoreGraphics"
"-framework UIKit"
"-framework XCTest")
set_target_properties(${NAME} PROPERTIES

XCODE_ATTRIBUTE_GCC_PREFIX_HEADER ${CMAKE_CURRENT_LIST_DIR}/Prefix.pch
XCODE_ATTRIBUTE_INFOPLIST_PREPROCESS YES
XCODE_ATTRIBUTE_IPHONEOS_DEPLOYMENT_TARGET 7.1)
I don't understand why it can't find the header file as I linked the frameworks, and I'm at a loss for the other CMake error and clang warning.

I'm new to Swift and the Package Manager. I'm following a tutorial that generates the Xcode project file, but I get errors when I run "swift package generate-xcodeproj" (or "swift package update" for that matter). Below is the output.
It looks like it doesn't recognise the 'uuid_string_t' type in hfs_format.h header file.
Any ideas on how to solve this? I'm using Xcode 10.2 and Swift 5 on macOS 10.14.4. My Xcode Command Line Tools setting under the Location Preferences tab is set to 10.2.

I had the same issue after installing Xcode 10.2 and macOS 10.14.4. Solution for me was to run the following commands in Terminal:
brew doctor, and fix the mentioned issues
sudo xcode-select --reset
After executing these steps I did a reboot, and build started to work again.
This is what my files look like
My main function is here
I compiled it using the following command:
g++ -std=c++17 main.cpp linkedList.cpp -o main
on MacOS 10.14 using the latest gcc compiler as of 2018.
It looks like the definitions for your template are not visible to the compiler when it is instantiated. You need to move the definitions from linkedList.cpp into the header file, linkedList.hpp.
(Note that C++17 support is still experimental in GCC.)
I have OpenCV 3.0.0 installed in /usr/local/opencv-3.0.0
I am trying to construct a CMakeLists file to build a library against this OpenCV 3.0.0. The CMakeLists.txt is as follows:
cmake_minimum_required(VERSION 2.8)
project(STT_People_Tracker)
cmake_policy(SET CMP0016 NEW)
# compilation mode setup
#set(CMAKE_BUILD_TYPE Release)
set(CMAKE_BUILD_TYPE Debug)
# set OpenCV directories - CHANGE DEPENDING ON SYSTEM
set(OpenCV_PATH "/usr/local/opencv-3.0.0")
set(OpenCV_INCLUDE_DIRS "${OpenCV_PATH}/include")
set(OpenCV_LIBS "${OpenCV_PATH}/lib/")
# set environment variables
set(SOURCES_PATH "${CMAKE_SOURCE_DIR}/Sources")
set(INCLUDES_PATH "${SOURCES_PATH}/include")
if(CMAKE_BUILD_TYPE MATCHES Debug)
set(OUTPUT_PATH "../Debug")
message(STATUS "Compiling in DEBUG mode")
elseif(CMAKE_BUILD_TYPE MATCHES Release)
set(OUTPUT_PATH "../Release")
message(STATUS "Compiling in RELEASE mode")
endif()
include_directories(${INCLUDES_PATH})
include_directories(${OpenCV_INCLUDE_DIRS})
# compilation of executables
message(STATUS "configuring executables...")
add_executable(${OUTPUT_PATH}/mainTest ${SOURCES_PATH}/mainTest.cpp)

message(STATUS "configuring libraries...")
add_library(${OUTPUT_PATH}/background_substractor ${SOURCES_PATH}/background_substractor.cpp)
# set linker options
link_directories(${OpenCV_LIBS})
target_link_libraries(${OUTPUT_PATH}/mainTest opencv_core opencv_highgui)
target_link_libraries(${OUTPUT_PATH}/background_substractor opencv_core opencv_highgui)
message(STATUS "cmake configuration complete")
It is a fairly simple Cmake file, however, I have the following problems/doubts:
1.-How can I know I am using OpenCV 3, and not other versions of OpenCV present in the system?
2.- When compiling the file background_substractor, its associated header file can not be located, although I have checked the path and it is correctly assigned in the set(INCLUDES_PATH "${SOURCES_PATH}/include"):
/home/alberto/STT_People_Tracking/Sources/background_substractor.cpp:3:36: fatal error: background_substractor.h: No such file or directory
#include "background_substractor.h"
^
compilation terminated.
make[2]: *** [CMakeFiles/../Debug/background_substractor.dir/Sources/background_substractor.cpp.o] Error 1
make[1]: *** [CMakeFiles/../Debug/background_substractor.dir/all] Error 2
make: *** [all] Error 2
3.- Finally, and if I comment the header file, I have problems linking:
Linking CXX static library lib../Debug/background_substractor.a
/usr/bin/ar: lib../Debug/background_substractor.a: No such file or directory
make[2]: *** [lib../Debug/background_substractor.a] Error 1
make[1]: *** [CMakeFiles/../Debug/background_substractor.dir/all] Error 2
make: *** [all] Error 2
I have tried everything: Specifying the include files in the add_executable() and add_library() commands, I have checked paths and they are ok, etc etc.
Could anyone more experienced with CMake, give me a little hand?
Thank you very much in advance,
Alberto
How can I know I am using OpenCV 3, and not other versions of OpenCV present in the system?
Your project should check that.
But usually projects just use find_package command for fill variables related to 3d-party library. This command perform all needed checks. In your case it could be
find_package(OpenCV 3 REQUIRED)
call, which fills OpenCV_LIBS and OpenCV_INCLUDE_DIRS variables automatically. This command, by default, search OpenCV installation in default paths, but you can adjust searching algorithm by using parameters to cmake (so, you needn't to change CMakeLists.txt when you build the project on other machine). E.g., this way
cmake -DOpenCV_DIR=/usr/local/opencv-3.0.0 <source-dir>
you can specify precise installation path of OpenCV.
When compiling the file background_substractor, its associated header file can not be located...
Cannot suggest anything aside from checking file existence
/home/alberto/STT_People_Tracking/Sources/include/background_substractor.h
But this also can be a result of the 3d issue(see below).
Finally, and if I comment the header file, I have problems linking...
Your usage of CMake targets is incorrect. Unlike to make targets, which usually are files, CMake targets are simple names. By default, name of library/executable target determines filename of the library/executable file, produced by this target, but this can be changed. Directory, where resulted file will be located, can be adjusted using CMAKE_<TYPE>_OUTPUT_DIRECTORY variables, where <TYPE> can be ARCHIVE, LIBRARY or RUNTIME depending on target type.
Correct CMake script would be:
cmake_minimum_required(VERSION 2.8)
project(STT_People_Tracker)
cmake_policy(SET CMP0016 NEW)
# compilation mode setup
#set(CMAKE_BUILD_TYPE Release)
set(CMAKE_BUILD_TYPE Debug)
# set OpenCV directories using find_package.
find_package(OpenCV 3 REQUIRED)
# set environment variables
set(SOURCES_PATH "${CMAKE_SOURCE_DIR}/Sources")
set(INCLUDES_PATH "${SOURCES_PATH}/include")
if(CMAKE_BUILD_TYPE MATCHES Debug)
set(OUTPUT_PATH "${CMAKE_BINARY_DIR}/Debug") # Use absolute path
message(STATUS "Compiling in DEBUG mode")
elseif(CMAKE_BUILD_TYPE MATCHES Release)
set(OUTPUT_PATH "${CMAKE_BINARY_DIR}/Release")
message(STATUS "Compiling in RELEASE mode")
endif()
# Set output directory for STATIC libraries and executables
set(CMAKE_ARCHIVE_OUTPUT_DIRECTORY ${OUTPUT_PATH})
set(CMAKE_RUNTIME_OUTPUT_DIRECTORY ${OUTPUT_PATH})
include_directories(${INCLUDES_PATH})
include_directories(${OpenCV_INCLUDE_DIRS})
# compilation of executables
message(STATUS "configuring executables...")
add_executable(mainTest ${SOURCES_PATH}/mainTest.cpp) # Use simple name as a target
# compilation of libraries
message(STATUS "configuring libraries...")
add_library(background_substractor ${SOURCES_PATH}/background_substractor.cpp) # Use simple name as a target
# set linker options
# Command below is no-op: OpenCV libraries enumerated using absolute paths
# link_directories(${OpenCV_LINK_DIRECTORIES})
target_link_libraries(mainTest ${OpenCV_LIBS}) # Variable OpenCV_LIBS contains OpenCV libraries needed to link with
target_link_libraries(background_substractor ${OpenCV_LIBS})
message(STATUS "cmake configuration complete")
I was trying to install clang_complete on OSX 10.9.4. However while running make I get the following error:
[ 66%] Building CXX object CMakeFiles/clic_add.dir/clic_add.cpp.o
/Users/bharat/Desktop/clang_indexer/clic_add.cpp:5:10: fatal error: 'clang-c/Index.h'
file not found
#include <clang-c/Index.h>
^
1 error generated.
I have clang, llvm-g++ and llvm-gcc. How do I resolve this error?
You can download source code for clang
svn checkout http://llvm.org/svn/llvm-project/cfe/trunk
The header should be in the include/clang-c folders, you can edit the cmake file and pass in the location of the header in the CPP flags (-I)
cmake file would be here:-
ycm/CMakeFiles/ycm_core.dir/flags.make
I'm trying to build a subproject with cmake (it's not an xcode project or even an app for iphone, the result is cross-platform console executable, which #includes some inherited from C++ abstract classes, written in objective-c++)
I'm using this guide to link mac os frameworks: http://www.vtk.org/Wiki/CMake:HowToUseExistingOSXFrameworks
and this macro:
macro(ADD_FRAMEWORK fwname appname)
find_library(FRAMEWORK_${fwname}
NAMES ${fwname}
PATHS ${CMAKE_OSX_SYSROOT}/System/Library
PATH_SUFFIXES Frameworks
NO_DEFAULT_PATH)
if( ${FRAMEWORK_${fwname}} STREQUAL FRAMEWORK_${fwname}-NOTFOUND)
MESSAGE(ERROR ": Framework ${fwname} not found")
else()
TARGET_LINK_LIBRARIES(${appname} ${FRAMEWORK_${fwname}})
MESSAGE(STATUS "Framework ${fwname} found at ${FRAMEWORK_${fwname}}")
endif()
endmacro(ADD_FRAMEWORK)
This is the important part in CMakeLists.txt
project(myprojectname)
........
add_executable(mytarget src/mytarget.cpp)
add_framework(CoreMedia mytarget)
add_framework(CoreVideo mytarget)
add_framework(AVFoundation mytarget)
add_framework(Foundation mytarget)
........
And that's what i have when trying to build:
WARNING: Target "mytarget" requests linking to directory "/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.0.sdk/System/Library/Frameworks/CoreMedia.framework". Targets may link only to libraries. CMake is dropping the item.

It actually finds all these frameworks, but can't link, which produces a lot of linker errors. I'm pretty sure that that's the reason because i made a testproj using XCode and it has the same errors till i linked all the needed frameworks.
When i just use
FIND_LIBRARY(COREMEDIA_LIB CoreMedia)
...
then COREMEDIA_LIB is set to NOTFOUND - what's going on? :/
I googled a lot but nothing :( Feeling pretty much lost there.
Got the thing: you have to link NOT the frameworkname.framework folder in the TARGET_LINK_LIBRARIES, but the fwname.framework/fwname file! Now it works that way.
The changed macro is this:
macro(ADD_FRAMEWORK fwname appname)
find_library(FRAMEWORK_${fwname}
NAMES ${fwname}
PATHS ${CMAKE_OSX_SYSROOT}/System/Library
PATH_SUFFIXES Frameworks
NO_DEFAULT_PATH)
if( ${FRAMEWORK_${fwname}} STREQUAL FRAMEWORK_${fwname}-NOTFOUND)
MESSAGE(ERROR ": Framework ${fwname} not found")
else()
TARGET_LINK_LIBRARIES(${appname} "${FRAMEWORK_${fwname}}/${fwname}")
MESSAGE(STATUS "Framework ${fwname} found at ${FRAMEWORK_${fwname}}")
endif()
endmacro(ADD_FRAMEWORK)
Hope it will be useful for someone...
